Magnetic properties of the diluted magnetic semiconductor Zn1−xCrxSe

The magnetic properties of a new diluted magnetic semiconductor Zn1−xCrxSe are reported. Specific heat was measured for 1.5 K≤T≤20 K and B≤3 T, whereas magnetization data were taken at T=2 and 4.2 K for magnetic field (B≤6 T) along (100), (110), and (111) crystallographic directions. The data are interpreted using the crystal‐field model for the Cr++ ion, including static Jahn–Teller distortion.
